Drinking this tea has not prevented me from getting colds/flu. HOWEVER, my cold/flu symptoms are always way less severe than those around me. In addition, I have noticed the greatest effect on my stress level and quality of sleep. Will continue buying this tea, and I have recommended it to friends and family.

This is the same tea that Dr. Mercola recommends, but at a better price. It has an earthy spicy flavor that just can't be beat. Plus tulsi has amazing antioxidant benefits. Also, for those celiacs out there I contacted the company and received a reply that their tea bag, all components, and the tea are all gluten-free.
